[Abbrev., “Problem Exists Between Keyboard And Chair”]
Used by support people, particularly at call centers and help desks. Not
used with the public. Denotes pilot error as the cause of the crash,
especially stupid errors that even a luser could
figure out. Very derogatory. Usage: “Did you ever figure out why that
guy couldn't print?” “Yeah, he kept cancelling the operation
before it could finish. PEBKAC”. See also ID10T. Compare pilot
error, UBD.
